GRAIN-CAR DOOR.

Appncamn mea March 29,1926. serial No. 98,274.

The invention aims to provide a new and improved grain car door, which will be rather simple and inexpensive, yet will be practicable and in every way desirable.

The door is mounted for swinging either to a closed horizontal position or to a vertical open position, and a further object of the invention is to provide unique means for holding said door in either of these positions.

Another object is to provide novel means for holding the door in any partly open osition which may be desired, said means orming part ofa brake structure, by means of which the lowering of the door to closed position, may be controlled.

With the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanyingdrawings.

Figure 1 is a perspective view showing the door in closed position in full lines but in dotted lines illustrating one way in which it may be held in open position.

Figure 2l is a perspective view illustrating the preferred manner of holding the door in open position.

Figure 3 is an outer sid'e'elevation. l Figure 4 is an inner side elevation illustratig more particularlythe action of the brake for controlling the lowering of the door'.

In the drawings above briefly described,

' numerals 5 and 6 designate the Stiles of a y car door frame, 7 designates aldoor for. lthe lower portion .of said frame, and 8 designates an initial discharge door for an opening 9 in the door 7.

The door 7 is preferably formed from a lsingle metal lplate reenforced byan angle metal bar 10 riveted to it, or by a number of such bars, one end of this door being provided with a bolt 11 to engage a keeper in the stile 5, when the door is closed. In addition to this securing means, the "upper corner portions ofthe door` 7 are preferably provided with studs 12 for reception in sockets in the inner sides of the Stiles 5 and 6, said studs serving to hold the l-door against end-wise creeping and .outwardfalli'ng, even though it'should break loose from the remainder of its mounting means, hereinafter described.

sist in opening and closing the same. y

tion last referred to.

Suitable handles 13- are of course provided on the door to asfasteners are preferably provided with safety dogs 18 for effectively holding them in locked position. Vl/Vhen the latches vare released, the door 8 may be swung outwardly and upwardly and then supported by hook 19 on the door 7, said hook being engaged with an opening 20 in the latch 16, in the present dlsclosure.

One lower corner ofthe door 7 is hingedn ly mounted as at 21, at the lower end ofthe stile 6, the hinge including a horizontal pivot 22 and a' vertical pivot l23. The door 7 -may be horizontally swung about the vertical pivot 3, against the inner' side of the car, as shown'in dotted lines in Figure 1,

and'it may be held in this position by means which will hereinafter be described. Up-

on4 the horizontal .pivot 22 however, the door may be swung to its preferred open position, as disclosed in Figure 2. 'Novel' provision is made for holding this door either in closedposition orin the open posi- This means includes a door-holding member 24 which is engageable with the upper edge lof the door, whether the latter be closed asin Figure 1, or open as in Figure 2, and a vertical guideway is' provided for said holding member, permitting it tomove to either of its operative positions. construction, the holder 24: is in the form of. a bifurcated arm projecting laterally and downwardly from a .vertically disposed In the preferred sleeve 25, said sleeve slidably surrounding a verticle rod 26 whose ends are laterally directed and secured at 26 to the stile v6.

When the holding member 24 is engaged i with the door 7, in either position of the latter, it holds it against inward swinging v in open in Figure 1.

v bent to provide a hookv29, the rod or track being anchored to the car side adjacent this hook, by any suitable means 30. When the door 7 is swung to the open position shown in Figure 2, the hook 29 receivesit and cooperates with the member 24 in holdingit osition.

A bra e lever 3l is connected with the door 7 by a chain 32 and is provided with a guide 33`.which under ordinary circumstances may loosely slide along the'rod 27, but when the lever is angled as shown in Figure 4, said guide will frictionally engage the aforesaid rod, so that an effective brake is provided for controlling the lowering of the door 7, as illustrated in Figure 4. Near lthe upper end of the chain 32, hook 34 is preferably provided, and by engaging a portion ofsaid chain -with said hook, after door 7 has 4been' upwardlv swung to any desired inclined position, said door may be held in such position. The chain and hook are also instrumental in supporting thev door 7 when it is horizontally swung inwardly against the side of the car and is lifted somewhat as disclosed in dotted lines By employin the novel construction shown-and descri ed or a substantial equiva-- lent thereof, a grain car door is produced which is-extremely simple and inexpensive,

y yet is practical, durable and in every way desirable. On account of these existing ad-` vantages, details-shown Aare preferablyfol-V lowed. However, within the scope ofV the invention as claimed, variations may of Icourse be made.

I I claim: 4

1. A locking means for a door pivoted near one vert-ical edge forwupward swinging to open position, said means comprising a holding member for engagement with the upper edge of the door when the lattes is in .either its closed or open position, and a statonaryvertical guideway along which said holding member is slidable to either ofits operative positions. 2. A 'holding means for a door pivoted near'one vertlcal edge to swing upwardly to an open (position, said holding means comprising a oor engaging member 'having :i carrying sleeve, and a vertically disposed rod slidably. surrounded by said sleeve to permit movement of said member to either of its two operative said rod being directe laterally for anchorage to a fixed support.

. 3. A grain car doory pivotally mounted at` one lower corner, the pivotal mounting of ositions, the ends of' said door having a horizontal pivot and a vertical pivot to permit the door to be opened by movement in either of two directions, a chain connected with said door and a hook cooperable with said chain forholding the door in an inclined partly opened position, said chain and hook being also operative to support the weight of the door when thel latter is horizontally swungI t0 open position and then slightly raised.

4. Means for controlling the closing movement of a downwardly closable door, said means comprising a track above the door, a brake lever havinga4 guide slidable along the track: and adapted to frictionally bind against the latter when the lever is moved to predetermined angular relation with respect to the track, and connecting means bey tween said lever and the door.

5. Means lfor controlling the closing movement of a downwardly closing door, said means comprising an inclined rod stationarily mounted above the normal closed position of the door and laterally of such positio'na brakev lever having a guide slidable along` said rod and adapted to frictionally bind against the same when the lever is angled into predetermined relation with respect to the rod, and a chain connecting -said lever-.with the door.

6. Holding andr controlling means for la door pivotally mounted near one vertical edge for upward swinging to open position, said means comprising .a vertical rod substantially in line with said edge of the door and having its ends laterally oilset for anchorage to the door frame, a sleeve slid- Vable alongFsaid rod andhavinga laterally projecting door-holding portion to engage thev upper edge of the door when the latter is in either open or. closedl position, a second rod projecting laterally from the upper portion of the first named rod and having 'its outer end anchored, a brake lever having CARL AUGUST J OHASON.
